Kesten's analysis in the case of Bernoulli percolation was relying on another scaling relation, sometimes referred to as Kesten's scaling relation, stating that
\(\nu (2-\xi _4)=1\)  for \(q=1\) .
It was observed in [1]} that this equality fails for \(q=2\)  (one can also check this using the table gathering the predicted exponents below). We will show that it should be replaced by the following generalized Kesten's scaling relation,
\(\nu (2-\iota )=1.\qquad \mathrm {({\bf R7})}\)
